how to assing a default values to a numeric range slicer

[LuisJ]

i everyone, i'm leaning power bi and i have been searching about how do the next:

i have a dropdown slice that is configurate by type of date

and a numeric range slice based in the same date data 

i want to know if is posible to if i select for example a "last year" and the numeric range slice take the range values but doesn't lost the dates before, i mean:

take the date between 21/09/2021 and 21/09/2022 

and in this case can choose dates before 21/09/2022 like 29/08/2022 or older

and change the date type to "custom" if other date is selected

i appreciate if someone can help me, i'm starting, i don't know if this is easy or hard, thanks a lot

@Greg_Deckler thanks for you help, but maybe i explained it bad, 

my configuration is 

i have a table (Dim_date) with dates from Ene-01-2000 and Dic-31-2030, and a table with name "Date_Range" that contains the dates by types

and the two slicer are based on Date_Range

but when i select a date, the previously date are disable 

so that i want is 

1) when custom is select keep the last range selected ( by type )

previous selected last 7 days

next only in the case if select custom keep the previous date, for example

2) when is selected any type take the range but don't disable the previously 

 in my case, the things in the line green are disable

i want 

is like to assign a value to slicer, i don't know if it is possible

@LuisJ Is your type slicer coming from a disconnected table? Please confirm if I understand correctly. You want to be able to choose something in your type slicer and use that instead of the range values but you don't want the range values to change from what the user may have selected. If you choose custom, then use the values in the range slicer. Is that all correctly stated? If that is what you want, use a disconnected table for your type slicer and then something along the lines of:

Measure =
  VAR __type = SELECTEDVALUE('DisconnectedTable'[Value])
  VAR __Min = MIN('Dates'[Date])
  VAR __Max = MAX('Dates'[Date])
RETURN
  SWITCH(__type,
    "custom",SUMX(FILTER('Table',[Date] >= __Min && [Date] <= __Max),[Value]),
    "Last 30 Days", [Last 30 Days Measure],
    "Last 7 Days", [Last 7 Days Measure],
...
  )
