Best tools to trade & manage box options?

Saw a couple of posts here about using box spreads instead of margin loans to get good rates. I read through everything I could – but actually implementing the trade seems super complicated and time-consuming, especially since I want some flexibility and need to roll the trade monthly

Are there any automated tools or trading platforms that currently offer easy trading & managing of box spreads as loans specifically? I have seen boxtrades.com (historical interest rate trends and a trade builder), sytheticfi.com (they seem to have a panel on real time data for open offers & rates), and Chatham Financial for the swap curve / future rate trends.

Any other tools around to make this trade easier to trade & manage?
