Add Tags to Device Selector

Dear Blynk team,
I am currently using Blynk to control several smart lamps I build using NodeMcus.
All of them run the same code.
I am using a device selector to change the controlled device when using any of my buttons, sliders etc.

The problem is that I am only able to control every device by it’s own this way.
If I want to control all the devices I would need to assign all devices in one room to one Tag an than create the same button, sliders etc. layout for each room (Tag).

To avoid this redundant layout it would be nice to add a feature that enables the ability to add Tags to the Device Selector.

Thanks for your good work.
