Can an intake form populate more than just a new horizontal row in a sheet?

I have timeline templates built out in a cascading fashion (with parent and children relationships) using "workday" formulas and a holiday list. I'd like to start the timeline off with an intake form. The customer would enter the timeline type (telling smartsheet which template to pull) and then the start and end date of a project. I'd need smartsheet to then enter those start and end dates for example in a specific column and row within my timeline template. Currently, I only see functionality for smartsheet to populate a new row horizontally, and always at the bottom of the target sheet based on the intake form. Is it possible to make it do what I'm asking?
