FFmpeg multiple drawtext filters next to each other

Question

I would like to draw text on a video with ffmpeg that

has multiple lines
some of the words in these lines are in bold text style while others are not
the lines need to be animated with the timeline option

What options do I have here? I know that when it comes to make some words bold within a line, I would better go with the subtitle filter. But as far as I know, I cannot animate subtitles, right?

That is why I am wondering whether I could use multiple drawtext filters next to each other. But how can I pass on the information of the width of one drawtext to the next one in order for it to match the correct coordinates?

"Animate" can mean so many different things. Can you explain exactly what you need the text to do? — llogan, Mar 21 '21 at 18:08
@llogan: Of course, sorry! What I meant: Move from point A to B in 3 seconds. — ansonthecaptain82, Mar 21 '21 at 18:37

Use the subtitles filter with ASS subtitles. The subtitles can be moved using the \move override tag:

Example ASS file:
