Not at the moment. Adding importers is pretty easy though. The problem with complex tools like SkyTools is understanding the variability of export files. Neither Jared or I are familiar with SkyTools (unfortunately) and sometimes there are a host of options that can change what the export format looks like. Understanding the breadth of these permutations is the only reason it takes any time really...
All that said, the target import system is really only meant to be used by folks that have a bunch of targets, supernova, asteroid hunters etc (typically 25 or more in one sequence)... What is driving you toward needing target import as a solution for your sequences? SGPro does currently have a couple fairly friendly ways of adding targets into a sequence (not super great when you need to add 25 targets, but pretty good otherwise).
