I understand your frustration as much as I understand how difficult (if ever possible) it is to tell which bet was made by which entity; by entity I mean not only a certain trigger, but also other bots, browsers, etc., basically any tool that can communicate with your BetFair account.
Any bet that you post can be something else the next moment: it can be split in several parts, part of it can be matched, and not at the price you requested; part of it can be rejected and so on, which makes it so hard to label it and do the follow-up procedures that rely on that label.
For that only reason, and not for the reason of me being old-fashioned or limited in any way, I cannot offer you anything in this department.
But if you do get to writing your own bot, that is certainly something you can equip with the multiple-strategy option.
