Linking a Logo Back to My SquareSpace Home Page from a 3rd Party Page

Hey folks, so here's the situation.

I am using IDX Broker, as a third-party MLS plugin, to display listings on a clients website. Once viewing the details of a property, the viewer is technically on an IDX Broker page, meaning the links to get back to SquareSpace must be absolute. I have gotten this issue sorted for the header and footer of the site, but have yet to figure it out with the logo in the top left. Currently, clicking the logo will take you to a default IDX Broker page, called 'Advanced Search.'

See this listing for example: https://shaunpearce.idxbroker.com/idx/details/listing/a636/X7002284/477-Meadowview-Road-Kawartha-Lakes-ON-K0L-2W0?widgetReferer=true

Question: How can I get the logo to return a viewer to the SquareSpace end of this site? 

I am happy to provide more info should anyone need it.

Thanks for your time.
