Add Place Category name in listing title

Hi,
I’m using Whoop, and for every single listing I noticed that in meta name keywords are shown all place categories of the listing (bar, museum, etc.).
I’d like to put them also in the title, but if I check on wpgeodirectory –> titles and meta I see all variables but not the ones of place categories.
Is something related only to Whoop?
How can I add what is shown in meta kewyords also in meta title? By adding variables to wpgeodirectory/titles and meta or through whoop customization?

Thank you in advance
