Customising Gridmarket Page Titles

Hi,
Just digging in some more with gridmarket child theme.
I'm looking to change the page titles from 'Our products' and 'Items in tag' to other settings.

I've discovered the templates (index.php / mp_product.php / mp_productlist.php / mp_store.php / mp_tag.php / mp_taxonomy and can see where to edit this.

My main question is, is it possible to make the titles dynamic. Such as a category page to show the title of the Category and the same for a tag page - rather than a hard-coded option.
I'm assuming there is a function that can handle this, but alas, its beyond my level of skill at this point.
Hopefully somone can assist. thanks
Paul
