Importing a few albums at a time fails

So, I am running into issues with importing my gallery 1 albums into gallery 2. I know there are memory issues and workarounds, but honestly I have no idea how to up the PHP limit with my Dreamhost server...so I figured I'd just do things the hard way and import the albums a few at a time. So, here is the problem: when I import several sub-albums, I can't figure out how to properly preserve the path. For example, if I have the following album hierarchy:

Main page
Album1
Album1.1
Album1.2
Album1.3
Album2

And I import the following:

Main page
Album1
Album1.1
Album1.2

And then do the following import:
Main page
Album1
Album1.3

Or this:

Album 1.3

...Album 1.3 will end up on the main page, losing its parent album information. I could just move things around manually, but the tree structure is pretty complicated AND I'm not positive the photos are all where they should be since I have this visible error.

What is the proper way to select folders using the import module to preserve the album hierarchy when importing sub-albums a few at a time?

Thanks in advance.
