It would be very useful to have this shortcut so that I can select ALL the links of ONLY ONE artboard so that I can easily and rapidly change the presets of the links at same time.

There is the short-cut control + A but my idea is to have a shortcut to select all the links related to one art-board when selecting one art-board (or even any other at same time). As user, I think that it would be logical to get this short-cut and so valuable. It takes too long time to select links of an art-board while I would like to put the same presets.
Also, allow us to have this short-cut and then un-select one link, for exemple, pressing "shift" to unselect the link(s) we won't like to edit at same time.

This shortcut is not available yet (I had this information confirmed by the assistance support) and I do not understand why as it would be so much easier in some case.
