Requiring multiple extensions via set script command upgrade?

[HashtagMC]

Cheers all,

I'm trying to balance a new command I wrote and in order to make it not OP, I want it to require the Trade Command Softwares Mk1 and 2, as well as the trading system extension. I tried simply placing a "set script command upgrade" command thrice, with each of the wares, but it appears only the most recent one is in effect (tested by removing the Trade Command Software Mk1 from my ship; the command was still available).

Is there a way, short of writing a check script, of requiring these upgrades all? I'd prefer the neater appearance of just a setup script and a plugin script, if possible (and to learn which way is the right way).

Many thanks in advance!

In X2 the only way is via a check script, only X3FL has options to set multiple upgrades directly.

Also, when using a check script you can have the command displayed but disabled, whereas setting the upgrade hides the command completely

Oh well.

Hiding it entirely would be desireable; there's really no point (for my use case) in showing the disabled command.
