Kortney,
We have had a couple requests for the GE SP option over the years. We've also received requests for T1 through T99 for Trees, S1 through S99 for Shrubs. We've even received a request for GEN spe and Gs, with the capitalization varying like that.
It is quite challenging assessing what is common enough to be added as a default option.
But regardless, every plant has a requirement of editing, in choosing the symbol, symbol width, size, remarks, and perhaps even modifying the common name to be more regionally accurate. Among that editing, setting the desired Code is a just one more minor step. The real power use of the software is then saving that plant list as a Template, and importing from there into future projects. In terms of efficiency, it's all about adding from templates and previous projects, instead of the master database.
