Changing the H1 title on a location page

Hello there

I have 2 questions which I think are both related to the Location Manager plugin.

I have created multiple cities on my website in the area of Berkshire (in the UK).

If I visit the Reading location page:
mywebsite.com/places/united-kingdom/berkshire/reading/

The H1 on the page is called “GD Archive”. Can I change that to be “Reading”? Ideally I want all of my locations have a clear title at the top of the page.

My 2nd question is around SEO. If I create a category called “Dog Walkers” and add some dog walker businesses in the “Reading” location. Can I have a URL which will show all Dog Walkers in Reading which would let me create a unique meta title, description, and H1? For example, “Dog Walkers in Reading”.

Many thanks,
David
