Omnicore - Modpos from WebApp

Part of an Omnicore webapp I'm making for a customer includes a manual mode step through of the auto program to insure nothing crashes before going to auto. This program currently has 4 different EOAs, 20 different jobs all with their own unique positions, and from what I'm told many more to come. I'd like to add extra logic on the app end to make sure tools, wobjs, tool ids, etc. are all correct before a position is taught.

Long story short, is there a way from the webapp I can modify a position. Something like below?

button.onclick = async function () {
    let position = await RWS.Rapid.getData(posName);
    await position.modpos();
