Help: NPC activable by one player at the time

[grobyczen]

As the title says, is it possible to make an NPC that can only be activated by one player at the time?

 

For example:

 

Player A clicks on the NPC.

 

Player B clicks on the NPC; then it receives a message: "Sorry, NPC is busy talking to player A".

 

 

Thanks in advance.
