Add external SRT on the fly

Hi,
Am I the only one who would love to have an external SRT file added manually to whatever I’m streaming at the minute? I have some old dvds that I converted digitally that didn’t have a sub track. However, I don’t even want to spend too much time to organize them all and find the appropriate SRT, I’d rather add an SRT when it’s needed.
Also, I normally watch everything in original language + ENG Subtitles (English is not my first language) and whenever I’m with my parents, I’d like to choose an external sub (another language) on the fly, an srt that I don’t have at the minute in the directory, but something located elsewhere.
Thanks
