Spring RTS Engine

Hello there,
I've found very useful widget on Unknown Files: Share Units Widget v0.8

Description:

Adds a command: "/luaui shareunits <Name/teamID>"

Can be bound to a key by adding for example "bind Ctrl+Alt+F1 luaui shareunits MelTraX" to uikeys.txt, everytime you press Ctrl+Alt+F1, you will give me your selected units whenever I'm allied with you..

I'd live to see a feature to also give resources to my ally in that way. Most likely, a function which gives to desired ally for example 20% of my metal or energy.

Would it be possible to write?
