OFP Units vs airframe units

Could we have an option to generate the OFP with the airframe weight units?

For example, I have a few aircraft set in LBS and I would like the OFP to be automatically generated in LBS, rather then the usual KGS I normally use.

What happens is that I usually forget and end up generating a new OFP with LBS (which leads me to forget to KGS the next time!)

Anything from an option to a reminder (OFP set in KGS with airframe set in LBS!) would help!
