No real need to delay this I'm happy to accept it on the basis it's an internal tool not designed to be user friendly I can always enhance that side of it myself. The alternative that I'm seriously considering if I can find the time is to create my own JAVA utility to do it. But given how little time I have that might take a while and I'd rather spend anytime I have modding.
I'd recommend just waiting until they release the Excel sheets. Paul showed some of the different sheets to me, and they seemed super effective, especially the tech tree one. They might need a bit of cleaning up and polish (I only saw the tools, didn't use them). Considering 1.1 isn't too far off (And IIRC Paul said the excel sheets would come with or around 1.1 in one of the dev streams), creating your own software would probably be futile since it'd be replaced almost as soon as you finished it.
