Is your feature request related to a problem? Please describe.

We have updated Russian Joomla Commuity portal from J3.10.12 to 5.0.0. and now getting it in order. Yesterday I tried a new J5 feature - Schema.org plugins. That's swag. But we have a 3k+ articles, different types... Some parts of them are creating from plugin - we parse our Telegram channel and copy posts from there to community portal to specified category automatically. And for each of them we must fill Schema.org data MANUALLY! It's crazy! And our site is not so big. We can find Joomla sites with tens and hundreds thousands of articles...

-- What can we do here?
-- Just die.

Describe the solution you'd like

I think there could be a system with predefined settings for each category of articles (for ex.). So, I'll say to Joomla:

Articles in this category are BlogPosting schema type only. Fill title from title, author data from com_contact, image from intro or fulltext image etc..., But for other category my articles are products because I did an overrides there. So article title is product title, that article custom field is product price, etc...

Due to schemaorg data is stored in separate database table may be we need a new bulk action in articles list for updating a schema org data for articles with category rules.
