Add property for multiselect

[margolyesh]

Hi!
If I select several items (for example, devices), open the properties window and add a new one, it is added only to one device, although it is written that multiselect is made.
Is this a bug or not?
In the same situation, the specialization and labels change for all selected items.

Setting multiple properties is not supported at the moment. We may implement it in the future.
