Categorize data based on 3 columns

Hi,
i need to create a colum that asigne a value based on other 3 columns.

for example, i have this data table

 

IDDateType
10001-01-2021   1
10002-01-20212
10003-01-20211
10005-01-20213
10102-01-20211
10104-01-20212
10103-01-20213
10205-01-20211
10210-01-20211
10211-01-20211



I need to create a new column that for each same ID and type it, assign a letter (from "a" to "z") depending on which came first.
The result should be something like this

IDDateTypeNew Column
10001-01-2021   11.a
10002-01-202122.a
10003-01-202111.b
10005-01-202133.a
10102-01-202111.a
10104-01-202122.a
10103-01-202133.a
10205-01-202111.a
10210-01-202111.b
10211-01-202111.c



Thanks
