Add more than 30 Labels

We are currently teaching our team to add as many labels as possible so that they can filter contacts based on product, profession and location. We are based in Australia so there are loads of locations to add. We do this so that if we have in person events, we can see who is in the area to invite to the events. It would be awesome if there could be an unlimited or just more than 50 labels that could be added.

Thanks!
