Possibility to go back to selected filter after its modification

Hi,

Consider the two following scenarios:

1) I select a custom filter
2) I edit the search bar for some reason

at this point I may want two different things:

 - update the selected filter with the modification I’ve made (ie: save changes as you said)

OR

 - go back to the original value (and so, results) of this selected filter

I’m far many times in the second case myself, but the two options should definitively be available.

To formulate it more accurately (and I hope, clearly enough): it is a matter of going back to the results this filter gives when it is selected when clicking on this already selected filter.

Clicking on the already selected filter should permit to do the first.
