How to link to title

My website is https://www.abennettphotography.co.uk

I want to be able to return to the homepage from any gallery by clicking on the title ie a.bennett photography (note, I don't want to add a 'home link to the navigation).

In the backend this is a text block (think) but I am unable to make this a link as there isn't an option to do this.

How do I make this a link?

Thanks for help in advance
