Automatic date in layout FBL1N basic

Hi,

I have a question related to layouts which can be made in t-code FBL1N.

Is there a possibility to set default net due date as current date + for example 4 days?

Also is there a possibility to set date like creation date to update everyday? Something like =today formula in excel. It will avoid changing creation date day by day in workflow. It will update automically.

Thank you.

If you need more details about this case please let me know. If Tag isn't related, please forgive me. It's my first question here.
