How to display products from several infoblocks using a filter in Bitrix?

Question

1C-Bitrix

Hello!
Tell me, please, how can I most easily display on the main list of goods by a certain property from 3 infoblocks?
I was looking for some ready-made component so that there would immediately be the name of the product, price, buy button and there was no need to redo anything, just stylize, correct the layout and that's it.
The first one I took was catalog.top, it displays everything perfectly as I need it, according to the filter I need, but that’s bad luck - as I understand it, you can’t display goods from several infoblocks there.
Then I came across a similar component store.catalog.top , inserted it, was delighted, displays products from several infoblocks, cheers, but not for long, this does not filter products only with the desired property.
Sorry, if I wrote a fierce stupidity, I'm just starting to learn what Bitrix is.

All (modern) standard components for displaying infoblock elements require you to specify the infoblock from which to select. As an option, put catalog.top into your own namespace and add your own filter to the CIBlockElement::GetList request in the component
