Logitech claims to have code to program Jeff Rowland electronics but - after four hours of trying myself and working with Logitech support- was unable to program their remote to control my 25 year old Consummate pre amp, either through a USB connection to a PC or by teaching the Logitech remote from my Rowland remote.
You might be able to program Logitech remotes for later versions of JR pre electronics (with small remotes).
....great support from Logitech
