Absence might only start when another finishes

Content

Hello experts.

I'd like to create an absnece type to extend an absence.
but since it is an extension it is treaed differently.

The start date of this entry (let's call it eType must be 1 work day after type A absence finishes.

How can I do it?
IF needed i might use it in the fast formula, but is hard still, to get this information.

Thanks
