Problem of position a subtitle in a .srt file

Dear administrator,

When I use infuse for TVOS to watch tv show or movie with .srt format subtitle file, I notice that some format function cannot be proceeded by infuse.
Would you please advise how to handle or waiting for future update?

Here’s example.
Thanks.

something like this?

Support for position tags is something we’re working on for an upcoming version.

May I know whether this problem has been fixed in infuse 5.2?
Thanks.
