If you want to prep a submission to the UBC Herbarium you can select the PTM numbers you want to submit.
ptm_to_herbarium(c("180", "192", "31"), tempfile("test_herb.csv"))
If you want to prep a submission to the BOLD with the same ptm numbers:
ptm_to_bold(c("180", "192", "31"), tempfile("test_bold.xlsx"))
Check the resulting files; some modifications might need to be done.
