[ICOM] Programming; Using the .icf file for 2 models

[Dave]

Greetings;

I am setting up the K5TCH (Texas Children's Hospital - Houston) station. 
It will be used for both emergency applications and also for special 
events for children.

Equipment:  6- T-90A HT's
            3- 2720H Tcvrs
            1- IC706MKIIG (no programming applicable for this model)

Question:

Rather than filling in the program "blanks" (quite a number of V/U 
frequencies involved) for the T90 and 2720 radios, can the same .icf 
file be used for both the T90A and the IC2720H?
If yes, how?

I do have the appropriate programming software for both models.

Thanks;

Dave, W5WP
