I so did not want to touch this post at all. Poor astronaut has copped his first c'mon son! or second maybe. At least your posts are getting more complicated generally astro, so thats means your getting into it and getting better. Remember work has its own rewards. Meaning your effort will be rewarded with a better outcome. It would have been quicker to actually rename sequence your self, instead of posting this request, dont you think? there are hundreds if not thousands of people using JJOS's and I do not thin a single one ever said omg omg it takes to long to rename sequence so I am gonna request that the sequence can have tempo in name.
If you thought about it, you answered your own question
just copy text when you name first track or sequence, then paste this every time you name a sequence. so copy 128BPM and you solved your problem
