Specifying investment import accounts

[Samantha Ahuja via KMyMoney-devel]

Hello, thanks for your work on this great software. I have a question
regarding investment importing options that are not apparent in the wizard
and are problem known only or mostly by developers. Normally it asks you to
pick which two accounts to use in the importing dialog after doing the
field matchup, but I was able to put “Account Name:investment1” in the csv
header. It was recognized and only asked me for the checking account. Is it
possible to specify the checking account separately in the csv as well?
Ideally I would like to specify different account combinations per
transaction line. Can any other data be specified in the cab that is not
shown in the import wizard? Such as tags?  Thank you!
