I’m not sure, but in the meantime, you could use an input dialog box, and whatever input is provided by the user, you can then use a switch->case to determine which subflow to run. I typically list out all options with numbers and then use the number chosen to define the next flow. Example:
Label:ReInput
input dialogue box to %UserInput%
1: New Customer
2: Update Customer
3: Delete Customer
Switch on %UserInput%
case 1 - run New Subflow
case 2 - run Update Subflow
case 3 - run Delete Subflow
case Else - display error message “%UserInput% is not a valid selection, click okay to re-enter ”. Go to Label “ReInput”
End Switch
good luck!
