Is it possible to pause (not delete) a share?

Hi,

We want to know if there is an App (plugin) or a known method where we can pause/disable a share without deleting it. We want to prevent users to see the share while the contents are modified without having to delete it and re-creat it afterwards (lot of users would have to be added again).

Thx in advance

No, this is not possible. The share receiver can decline a share which brings it into an in between state, but not the sharee.
Would recommend to work with a custom/system/LDAP group, that one can be shared and unshared with just one action.
