Setting Parameter Default Value

I have created a number of 'What If' parameters withiut setting a default value, and I now find that I need to set a default value retrospectively. Is there a way to do this AFTER I've created the parameter? I can't seem to find a way to access the details of the parameter to amend them, only in DAX, and that doesn't seem to allow me to add a default value, e.g.


% People living with Dementia, living in care homes = GENERATESERIES(0, 100, 1)
This shows my minimum and maximum values, plus the values of any increment, but not a default value - can anyone help?
Thanks in anticipation,

@Buckswriter you will have a measure and change the default value in there


% People living with Dementia, living in care homes =
SELECTEDVALUE('% People living with Dementia, living in care homes'[% People living with Dementia, living in care homes], <<this is where default value goes>>)
