Send downlink to devices using one same push button.

Send downlink to devices using one same push button.

Hello, 

I have few dragino LHT52, currently i  am using separate push button and separate analisys to send downlink msg
What if i want to send same downlink msg   (change time interval for let say 10 minutes - payload will be the same, for all of them) using one push button and one analisys. 

Is it possible ?
