Automatically Change Featured Product By Tag?

[cpk_jenna]

So we have a weekly sale on a single item which is displayed on our homepage using the Featured Item... box... thing? (Technical term, I am obviously quite savvy.) The item changes every week, and the sale part is done automatically through the Sales & Discounts app. What I'd like to do, is also have that featured listing automatically change on the homepage so I don't have to be manually switching it at exactly 6pm on the dot every week. The app can apply (and remove) tags to the listing for the duration of the sale.

So (tl;dr) my question is, is there anyway to have the item in the Featured Item box thing display based on my WEEKLY-SALE tag? 

If that makes sense? I'm probably make this a lot more complicated than it needs to be lol. I seem to only be able to set by specific item and not by tag. Or if there's any other way to achieve this? 

Thanks in advance for any help!

Oh, sorry, I'm not really comfortable with that 😅 I thought you meant it was something you could walk me through here.

My mistake, thanks for your time anyway!

That would be great 😊 If you don't mind providing the code, I could make the adjustments to my theme files myself. I really appreciate your help!
