Hey @andreasgan , Thank you so much for the pull request, it looks good I will test it out and generate a testcase on it.

Quick question, was wondering would it be a better option to create all the table skeleton on a YAML and then let user pick to what he wants to customize or delete what he doesn't need ?.

i.e something like mock custom --create-plan-for-all-database

or this seems like a better option

I think yours might be better, since the YAML options would create a long list if there are too many tables ( and too many columns ) so navigating on it would be a pain.. I will test it out and approve it , thanks again @andreasgan

Adding --all-tables would not be a replacement for this, but its still a good idea.
Saves you from having to do `mock custom --tables a,b,c,d,e,f,g,h,i,...."
