Hi there,
You could call a microflow that changes the range based on the enumeration used for the dropdown:
For the month option, for example, I've stored the start and end date ranges by calculating the first and last day of the last month:
For the "Last Quarter" option, it was more difficult to obtain the exact quarter, so for now I've kept it to the last 3 months:
You can then use these two values to determine a range for your date picker:
Hope this helps,
Liam
