iTunes match - Can i increase the device authorisation limit?

Hi

I like most people have more than five apple devices running around the place, I would like to access my music library on all of them, ie more than five.

I have a 2TB subscription to iCloud but could not use that for sharing my music library which is a bit of a shame IMO so after looking at the support options I have set up iTunes match to solve the issue but hit a problem.

I am limited to just five devices so cant add all of my devices and access my music library on them as I wanted.

My library includes lots of old DCs and tracks that I ripped to iTunes years ago when it was first launched for the iPod so I want to keep the functionality of sharing the tunes across all devices and not limited to just five and have the agro of reauthorising and re authorising each time.

Any help appreciated.
