[Spell] Select Hero/Select Unit priority for shops

[Barade]

My map contains shops which will automatically select units/heroes like regular shops.
However, the heroes in the map have different bags which are heroes as well and are always automatically moved to their location.
It is a bit annoying when the shops select the bags/backpacks automatically since the hero should always have a higher priority.

Is there any way to force the shops to first select the hero and not the bags?
The upri (Priority) field is already set to 0 for the bags and for heroes it is 9 but that dos not help.
Is it maybe the delay from the auto moving every 0.03 seconds which causes shops to then select the bags?

Is there any way to detect the select hero/unit event from the shop and then to order it to select a different hero/unit?

You could try tinkering with classifications, e.g. making their backpack mechanical and make the select hero ability only work with organic units, but it's a wonky ability so not sure if it adheres to targets allowed

If it doesnt do any harm Id make the bags Is a Building True and tick the Any Non-Building Interaction Type on the Select ability.
