Is there a brokerage that’s actually a mix of M1 and Robinhood? (Pies + Instant Trading)

Does a "perfect" brokerage actually exist?

I’m currently split between M1 and Robinhood and it’s a massive headache. I’ve reached the point where I’m spread too thin and tracking everything on a manual spreadsheet just to see my actual allocation, which sucks.

**The M1 side:** I love the "Pie" setup for organizing my long-term stuff, but I’m over the trading windows and the way their auto-investing works. If one of my high-conviction stocks starts ripping, M1’s "dynamic rebalancing" basically stops buying it because it’s now "overweight." I want my recurring buys to stay at the fixed % I set (e.g., if I set 10% to Apple, I want 10% of every deposit to go there regardless of the current price).

**The Robinhood side:** The UI is obviously great and I love being able to set limit orders for flash crashes or just buy instantly. But managing a "custom index" of 15+ stocks on there is a nightmare. I don't want to set 15 separate recurring buy orders and manually rebalance them every month.

Basically, I want:

1. M1-style Pies/Baskets (for organization).
2. Fixed-ratio DCA (every $100 deposit splits exactly how I set it).
3. Instant execution / No trading windows.
4. A UI that doesn't feel like it was built in 1995.

I’ve looked at Public and Fidelity Solo Baskets but haven't pulled the trigger. Has anyone found a platform that actually hits all of these? Or a way to consolidate this without it being a second job?
