Importing parts of an imscc which exceeds my 500MB quota

Dear Community

I was made redundant from my Director of Music job after 13 years.  In that time I put a lot of energy into producing resources for Canvas.  I'd like to continue teaching privately using my resources, but cannot import my courses because they all exceed 500MB and even if I try and select specific content is still gives me the exceed warning.  Is there any way around this please?

Many thanks
