Select the same UV channels for selected objects.
Select the same UV channels for selected objects It's just strange to do not have this function. It can work with Alt+click hotkey, like all other parameters in Blender interface. Just Alt+click and you change UV channels on all selected objects.
Here is the proposal with several UV channels.

The problem is that Blender have no 1,2,3,4 .... UV channel< but some named UV data. So if same 1 of 2 channel UV's on two objects have different names you can't handle both at same time. Kind of good looking system if we talk about data but cause problems in most of workflows.
It will be better if it work as 1,2,3,4... UV channels with of course some custom names. It work like this everywhere but not in Blender what cause sometimes problems.
Same problem when you merge two objects but their UVs have different names - it make one objects with 2 UV channels instead of merge this two together because they both was 1'st UV channel.
So conclusion - we need UV Channels instead of some named UV Data blocks.
* @IIIFGIII * Having named channels is useful for node groups, keeping things flexible. The UV map node or attribute node can point to the name of the channel, and you never have to worry about which slot its in or how many total there are. Of course, UDIMs will be a better long term solution to most of our UV woes!
If I may, I'm currently coding an addon which can help you waiting for such a functionnality github.com/Vinc3r/BlenderScripts/releases/latest You'll get a warning if some meshes doesn't have desired channel.
For now it's limited for UV1 & UV2 activation on selected objects, but I can tweaked this to enhanced the UV number, why not.
