Request: Notion custom rules GUI should read ExpressionList.tpk for techniques instead of hard-coded list

The hard-coded techniques list doesn't include all of the available techniques that can be tested by custom rules. For example, Custom Sounds 1-10 aren't on the techniques dropdown in the custom rules editor, but they are still available to be entered using apostrophe, and it will work if manually entered into the prules xml and imported as a ruleset. But if I edit the ruleset in Notion, all techniques not listed in the download are broken (actually, they are changed to Circle Symbol).

Also, it can be very useful to customize the expressionlist.tpk file to add additional techniques. For example, I'm writing a ruleset for a vocal library and I'm adding the available syllables in the library to the list of techniques. This works if the ruleset is created in xml, which is what I would do anyway, but I can't tweak the ruleset in Notion because the techniques not listed in the dropdown will all be broken.
