What do you mean by regularly? You will have to manually send unless you did it programmatically. I'm not sure If it can be done through the GUI but you can do it from the console:
sendmany "" '{"address2":0.1, "address2":0.2}'
The first "" represent the default account, address1 & address2 represents the addresses you want to send to (you can add more) and the 0.1 & 0.2 are the amounts being sent to these addresses.
