Can we offer tiers free as an offer?

Good Morning,

Is it possible to offer your Tiers for free for a certain limited time? I see the Offers tab and I see where it allows you to create your own but I’m not sure if this is possible.

Our thought is: Offer our Tiers for free for the first month and after that, the monthly requirement would begin. This also would help during the COVID situation we are in.

Thank you!
