Adding additional Solar Tab320 with Factory Lithium

I know this is has been discussed in past and I believe I have a good understanding but wanted to do one more confirmation.  I have 2023 Tab320 with Factory Lithium (2 100W). The factory 100W solar is connected to the MPPT 75/10 and works great.  As I understand it, if I want to add a temporary (suitcase type) solar when needed (likely just 200W portable max), I will add another MPPT and I plan to go with the 75/15 since it's not much more.  I'll do some type of connection or passthrough of wires through the Nautilus and connect directly to the NEW MPPT 75/15.  From that MPPT, I simply wire direct to one of the Lithium batteries using a 30amp fuse before the MPPT and another before the battery (that's what is on the current factory setup).  The negative would go directly to my Ground box next to battery with Positive (red) to one of the positive terminals on lithium. This is allowing me to run them both in parallel?  Please confirm it would be that simple and nothing more I would need to do (other than adding to my Victron app)?  I only plan to add the additional solar when boondocking for extended timeframe.  Very much appreciate it.
