Pendo guide with iframes with different subscription ID

Hello,

I'm having trouble getting the Preview Guides to show up within an iframe. We have a parent app which loads different product iframes. These product iframes have their own subscription ID.

I read this guide https://support.pendo.io/hc/en-us/articles/360033277072-iframe-support-with-the-Visual-Design-Studio but Rule 4 says that the subscription ID must be the same between the parent and the iframes.

Is there anyway around this? We only want to show guides specific to the app and don't want to associate all guides to the parent app. 

Thank you
