Sales Engagement Tracker

As an AE, my org doesn't have a budget for an SEP (ex. SalesLoft, Outreach). Though, our SDRs are using Outreach. This leaves me to track and manage my engagement manually. Given, I'm not prospecting nearly as much as the BDRs/SDRs I still want to be organized.

Any recommendations on a basic spreadsheet tracker for cadence/sequencing? Or something else usable for an individual user?

Appreciate any ideas or something that's worked in similar circumstances.
