Serializing an asset as a serialized property

Hello,

I am working on a sort of karaoke module that allows me to have an audio file and a .srt file to show text that highlights when pronounced. I will end up with multiple lists of these objects that ship the method for reading and need to save these lists as separate custom files.

I am wondering if it is possible to save an audio asset (and of course text asset) as a serialized property like other atomic and non-atomic properties. I'm also asking myself about alternatives - if this solution is not possible or not very efficient.

Thanks in advance for any reply.
