Workarounds for click+drag via Screenshare (VNC)

Hey there, pretty new to UE4 but I often like to work from a 27" iMac to screen share into a machine with much better GPU resources. The iMac has a glorious display and is situated somewhere thats nicer to work, but has an incompatible GPU. The other machine has a GTX980ti, but is separated from me by about 30m of ethernet and must stay where it is, so Target Display is not an option.

The issue I have is that I cannot drag anything via Screen Sharing in the Unreal Editor. I work this way for a lot of other programs and this issue is specific only to the Unreal Editor.

At this point I can only move objects by typing coordinates into the transform fields which is no fun.

Has anyone else encountered this that can suggest a workaround?
