Usually the reason that language is there to allow for capital call lines. You would probably need to specify this or work with your IC if you have one to get this done.

One final thing on this, I’m not sure that a bank would loan you the money for something like this. Banks are super conservative and the amount of paperwork that you would need to make this happen is probably prohibitive.
