Grid bots starting price

Why does the grid bot needs to be set up manually for each trading range? It would be more easier to just set up % deviation up and down, number of grids, click start and auto sets up the grids.

Also it would be very nice a start/stop webhook.

Some will say that combo does all that and more, but combo has a minimum spacing between grids of 0.3% and is a bit much for me in btc trading.

With a lower spacing than 0.3 %, you will only pay fees and therefore constantly lose funds.
