Additional registers for already mapped modbus

[PolymorphedCust]

Hi

Is there a smart way to add registers via a new/longer profile, than what the original profil was? 

I made a profile for a modbus component, thinking I was only going to monitor the device. Now I want to be able to write to a few more registers. 

Can i make a profile for the device with the new registers and add it to the same IP and the same modbus Address in the modbus list, without messing with the already funcioning mapping?

Thanks
