Clear only certain entries in persistent data

Question

I am trying to allow 2 peripherals to bond to a central, and would like to be able to use 2 push buttons to delete the bond information for either device. Is it possible to clear the persistent data selectively like this?

Could this be a solution? 
 Button 1 is pressed to allow bonding to device x. 
 Wait for the bonding procedure to complete. DM_EVT_SECURITY_SETUP_COMPLETE 
 Use dm_handle_get() with the connection handle to get the dm handle of device x. 
 Tie the dm handle of device x to button 1 and store it persistently. 
 On boot, check if button 1 has any handle tied to it.
