Just checked in with this, and would like more linkage between SLA options and companies; while you can set the company SLA via API, this doesn't actually add it to the list of companies in a particular SLA. And there's no API to manage SLAs.
When adding 800+ organizations, this makes SLA management basically impossible; there's no way to assign, say, half of them to SLA programattically or easily in the existing GUI interface.
