Possible to pull a list of CIKs all at once without manual input?

[hohoCode]

First of all, thanks for the opensource. Great tool.

Currently it requires users to input CIK manually one at a time. Wondering if this is possible for the tool to pull a list of CIKs all at once? For example, the tool can take in a txt file which has a list of CIKs, and generate one or more CSV files as the output.

Thanks.
