3CX Live Chat & Talk How many URL can set?

[Eglobal]

Hi,
have problem with 3CX Live Chat & Talk - I can set only 7 uRL in this plugin no more can set on it. Maybe have some limit on URL? Or can change to some regexp to add more URL?
For example if have a page 1.sss.com and 2.sss.com and 4.sss.com - how it can be merget in to 1 URL?

Thanks
