extend group property

is it possible to extend the use of group property to not just share event between control ?
 
I know some programming tools on windows that they allow a control to set multiple group . their group provide more function .

group can be use to assign same property of controls .
for example I have 3 button and 3 textbox with same group call gr_test .

I can call the same property from these control using group .

gr_test.visible = false
or
gr_test.enable = false

this is very useful and safe alot of work .

I hope to see this in  future release
