Header Logo to direct to another page than "home"

Hello guys, 

I am not a coder at all and already contacted support before posting here... So here I am. 

My problem is : I'd like to have a cover page to anounce that I'm droping my collection soon with a custom background etc... But the thing is that whenever I click on the logo in my header it brings me back to the cover page and I'd like the header logo to be linked to my "shop" tab. 

The support advised me to use a custom code but I have no idea on how to do this... If you guys have any ideas please let me know.

Thank you very much,

with kind regards.
