When I purchased my boat last year it had a tear in the trampoline in exactly the position you describe. Perhaps the close proximity of the not-so-stretchy diagonal seam and the edge of tramp results in a lack of ‘give’ in that area. I know I often put my knee of foot down on that part of the tramp when sailing in light airs or stepping over the front on approach to the shore.
Anyway..... my tramp also looked to be the boat's original, so was quite saggy and UV-degraded. I opted to bite the bullet and buy new tracks and tramp from Windsport. It’s not cheap, but the result looks good and the boat is much stiffer and noticeably quicker - or maybe I've just been luckier this season
Removing the old tramp tracks was an eye opener - the deck underneath had large holes and cracks - the starboard hull in particular had been letting in water on windy days and I could see why. If I hadn't replaced the tramp, the whole track would probably have pulled out soon enough.
I whimped out of fitting the new track - Steve Sawford did the job whilst giving the boat the full restoration treatment. The quality of Steve's work and final result (including new tramp) transformed the boat - well worth the investment on both counts.
If you buy the new tracks there are matching stainless sliders for attaching jib blocks (as Martin mentions above). Although these also aren't cheap it’s worth buying them up-front. To fit them later will (I believe) mean removing and then replacing the riveted end caps from one or other end of each track.
Anyway, it sounds like your tramp may be newer and in better condition than my old one, so a good local sailmaker is probably the way forward. On the other hand, if your boat leaks like a sieve and/or your tramp is saggy it might just be worth investing in a new one.
