GI lists are essentially simple to create, if you have experience with bash, perl, or any programming language that you can use to format text, you may be able to automatically pull the GIs from these files and put them into a GI list. A GI list is simply a text file with one number per line, and each number is a GI. There may be some utilities that do this automatically (i.e. FASTA->GI list), though I don't know of them.

Alternatively, a nice way I've found for creating GI lists based on queries is to query NCBI for the data you want. You can do a search in NCBI, click send to on the top-right corner, and export it as a GI list. This is a nice, easy way of getting a GI list for blast subsets, though it's difficult to automate.
