extend enforced sharing expiration date

[wiswedel]

As a member of an entitled user group, I want to be allowed to extend an enforced share expiration date by another amount of the originally enforced timespan.

Example:

• default enforced expiration date: 7 days
• share a file on 1st March > expires on 8th March
• decide to extend the expiration on 7th March > new expiration date: 14th March

Background: Without an extension possibility, I'd have to create and send out a new link.
Permission to extend should be limited to certain groups.

Permission to extend should be limited to certain groups.

Should be all with share permissions, otherwise you just force people again to do the workaround you described already.

I am going to close this since there doesn't seem to be a lot of interest (no upvotes) and no respond since around 2 years. Please reopen if you still want to implement this.
