Add with unable to delete previous entries (days)

Hallo programmers, I have a one question, but not sure, if its possible. I have a Registrated users, they can add or delete all entries. Is it possible, that they could only ADD entries and no delete? But only Registrated users.
OR, and I would really prefer this, they could ADD, delete or whatever as normal, but without possibility to change previous (days) entries.
Thank you for your help.

Current version of plugins grants both ADD and DELETE access right at once, so it not possible here.

In case of standalone scheduler - control is more granular, you can define any complex access rules.
