I want to do some changes on workforce modeling

Hello,

In actions list in workforce modeling I want to do the following:

1- In actions list: I want to remove: Terminate - create requisition.

2- In " Edit Worker Assignment " I want to do the following

a- remove: Off Cycle Promotion & Annual Promotion from the list

b- Working Hours - Change to be hidden.

3- I tried to change the position for an employee and put him on another position, the FTE for new position is 1 but the workforce modeling transferred him without any restriction or validation, who come?.

Thanks
