Will the import function allow adding multiple levels of relationships all in the same import or will it still require multiple imports to accomplish this?

for example, we import all of our incoming freshman parents, both father and mother. The remaining information such as the student's name, class year, and each parent's business org name and position are all dumped on the attributes tab temporarily. Currently, I have to create many separate imports to move this information from the attributes tab to the appropriate area. Import 2 adds the business info for parent 1, import 3 adds the business info for parent 2, import 4 adds the student relationship, import 5 adds the parent year to the attributes tab, import 6 adds the college relationship info (college name and class year) for the student using that relationship id, import 7 adds the marital status for parents with spouses listed.

Since there are multiple layers of relationships needed, we were never able to complete this process with just one import. Much of the data is manually filled in on the import file such as the College name, relationship and reciprocal, etc. Global adds are used to add addressees and salutations.
