If it's within the same brokerage just ask for a block account(?) that way you will get the same thing in both accounts. Let me know if you are under a different arrangement and will try to be a bit more creative.
@HENRYFOSTER I am struggling a bit understanding what you mean you say "execute on my account". My impression was that you trade and place trades and you want it to be copied into your other accounts, or accounts you have POA over. Who's signal are you trying to copy?
