[Plugin: Multi-column Tag Map] change “exclude” command to “include” command?

Hi there,
really a great plug!!
I’ve got a question for Alan:

Is there any way to change “exclude” command to “include” command?

EXAMPLE: i’ve a big list of tags in witch there are some Brands’ name. Now, if I need to have a page that list only these names I have to tell the plug-in to show just these tags…

The “general” tags list is very big and it grow continuously, then to use the exclude command every day to keep the Brands’ list clean is almost impossible….

Can you help me please?

Thanks in advance

Bye
