Termination Screen – Field Reordering and Default Termination Date

We have a requirement on the Termination screen (Redwood) to reorder the fields so that Termination Type and Termination Reason are displayed at the top, before the Termination Date.

Is it possible to configure or use Visual Builder to reorder the fields?

In addition, can the Termination Date be defaulted based on the Termination Reason selected?

for example, if "Within Probation Period" is selected as the Termination Reason, the Termination date defaults to 15 days from the current date

Thanks in advance
