Summary Function Between Business and Pro

Apologies if this is the wrong area to post this…

I am a one-person shop that uses Smartsheet to manage various tasks. One of these is the PTA where I volunteer as a board member. I would love to use the dashboard feature to track certain metrics (parent attendance at events and our performance in fundraising) and show these at our monthly meetings. However, dashboards are mostly useless without the ability to summarize certain columns or rows (i.e., the Summary function).

I'm fine with purchasing a Business license, but I do not have three employees (so, there is no need for three licenses). The costs to purchase three licenses would be rough, especially as they'll go unused. I guess I'm curious why such a base piece of functionality is kept away from small organizations who love Smartsheet. Are there any plans (even as a purchasable add-on) to get th summary function without having to buy three licenses?
