SEIV: 1000 maximum launched units?

[Beorne]

I see that SEV is still very buggy, so I'll stick another while with SEIV.

I've just found there is a 1000 launched units limit. This is a big problem for me, I desperately need to launch some mines to protect some young planets.
The question: is there a way to selectively destroy satellites or mines in space? I have 30 satellites of 5 different type and I'd like to destroy only the obsolete one. Is this possible?
And for the mines, If I have 100 mines I have to destroy them ALL?

Thank you

That is a game setup option; setting it to 20k before you start is a good idea, just like in SE4.
