Are there any formats to import titles with multiple text styles in Premiere Pro?

Are there any text-based formats (xml, srt, txt) that can be imported to Premiere Pro preserving multiple text styles in a single title/text?

I want the text, for example, have the first word to be 24pt red and the second word to be 16pt black, in a single text (i.e. in a single text clip on a single track).

I'm trying to programmatically generate a text file, then import to Premiere Pro, instead of manually editing each text in the Premiere timeline.

I understand that the fcpxml format from Final Cut Pro X seems to be able to do that, but cannot be imported to Premiere Pro.

For ease of use, I need it to be able to import to Premiere directly instead of going through a different software like Davinci Resolve.
