Creating a psudo-column on a table to show the sum of two other columns?

Scenario: New Record Page with Related List.
Real-life: Purchase Order with Purchase Order Items.

Purchase Order Items related list/table has Item, Quantity, and Price Each. On the Purchase Order Items object we have a Total field that is a formula(Item * Price Each).

I would like to simulate that Total field client-side so that the call center folks can see line item totals before hitting Save.

Is there any way to do this with custom renderers / snippets? I'm fresh to Skuid and haven't gotten a great grasp of the dev tools yet.

Thanks!
