Feature Request: Customizable Target Quantity in DCA when triggered by webhook

What is possible:

1: In the web interface I can initiate a market buy for a certain % other the total balance triggered by a Tradingview webhook as well as multiple DCA buys when the price drops for a custom target price % with a custom set target quantity.

2: In the web interface I can initiate an initial market buy for a certain % of the total balance triggered by a webhook from Tradingview as well as DCA buys for the same target quantity (because its not an option to choose) by the same webhook trigger from Tradingview.

My feature request:

One webhook trigger from Tradingview that triggers market buys for as well as the initial buy at % of the balance as well multiple DCA market buys with a custom set target quantity triggered by the same webhook.
