Blu-ray video and data on the same disc

I hope someone can help me out here. So I'm preparing to do some backups of some things to Blu-ray discs. Most of the contents of the disc will be data. However, in part because some contain videos (as files, not as Blu-ray compatible "movies"), I'm hoping to add a small 10-30 second segment on each disc that will play if you put it in a player which basically states that it should be used in a computer instead.

(Think like how older game discs used to have a dedicated track telling you not to put them in CD players, or DVDs which would have bonus features you could access by inserting the disc into your computer.)

I scoured around finding little to no information on this topic. From what I can tell Blu-rays are movies OR data, and it's difficult to make it do both on the same disc. Does anyone here have any advice on how to do this and what software to do it with?
