New Post: Update issue notification list on project notification modifications

It would be great if when we modify the project notification list all the project issues notification lists would be also modified.

For example project P1 as notification list set as users u1, u2. Project P1 issues i1, i2, and i3 have so users u1 and u2 in their respective notification lists. Now, if I add u3 to P1 notification list, I'd like to automatically get issues notification lists for i1 and i2 adding u3 in the list. Respectively, if I remove u2 from P1 notification list, it should be automatically removed from P1 issues notification lists.
