It depends on the specific file handling and conversion steps, but, as a general hint, many subtitling tools support frame rate conversion from/to typical values, so, you load your subtitle file, find 'frame rate' or 'time base' conversion, hit '23.98->24', and that should solve the issue.
Why are you editing in 23.976? Are these features that are created also for Bluray or broadcast, and the 24fps version is only created for DCP? So I guess, the subtitles are used for both Bluray/Broadcast, and DCP?
Then the only solution is to indicate the frame rate reference in the file/project names, and do a 23.976->24 fpsconversion as indicated above for the 24fps version.
I know that some people actually do this time conversion in EXCEL, if their subtitle file is in an Excel file or EXCEL compatible. But, as I wrote above, there are tools that compute these typical frame rate/time relations immediately.

I can only speak for 'features' that go into the cinema market. Usually, most 'films' are made for cinema, and will be shown in cinema first. Also, with regulations towards hearing and visually impaired people, more and more features need to be presented with captions, subtitles, HI/VI tracks already in cinema. So, it is natural that working on HI/VI and captions/subtitles begins during the prostproduction phase and cinema mastering, because these add-ons are needed for the cinema release already. At that stage, the footage is probably 24fps most of the time. Except when for some reason the major capture format was 23,976 (e.g. using non-strictly pro cinema cameras). So, I guess, for these reasons, most of the time, editing time base for subtitles and captions will be 24fps.
In your case, that may be different, and the DCP creation may be a side path chosen once the major post production and mastering phase is over. In that case, the 23.976 conversion for video, audio and subtitles should probably be a combined effort towards the DCP. Do you create DCPs yourself?
