Deployed laser designator uncontrollable

After restocking a supply bag, the currently deployed laser designator becomes unusable because it shares the same key binding as zoom on the currently hand-held laser designator.

The expected behaviour is that it is possible to both use the laser designator as binoculars and control the tripod version after restocking at a supply bag to receive a second designator.

In the attached screenshot, you can see that I have a laser designator deployed on a tripod ahead of me. I also have one I am holding after standing at a supply bag. I can only control the one I am holding, since the right mouse button zooms in the binoculars. I cannot control the tripod one.
