Plesk and WordPress table names

Hi

I've recently started using Plesk to create WordPress websites and I have come across 2 problems with the table name prefixes

1. Plesk ignores the value I put in and creates a random string of letters
2. The random string of letters is mixed upper & lower case. MySQL recommends that table names should be lower case. I've come across a problem when moving sites between Linux & Windows as Windows ignores the case whereas Linux doesn't

Is there a fix for these issues please?

Thanks
