for me it's easier to have a full set of kits in the game menu...
Me too.
However, it is indeed much faster to add just 1 UCL overlay for let's say 2009-10 than to add those badges to 32 teams x 4 kits individually.

@ACICOG while we're here talking about kits, can we please get more kit combinations for NTs in CP14/16?
I know I may be a bit biased cause somewhat colorblind but we really could use more to be able to distinguish teams on the pitch.
Right now we only have the color combinations which were actually used IRL, but in the game any team can meet any team and e.g. Germany 2018 really needs a full white kit to be able to play against Croatia 2018 or Uruguay 2018, for me all current combinations are just colorful mozaic on the pitch:
Similarly, when I try to play Argentina 2006 vs Japan 2006 or USA 2006, I can't, any combination is blue and white:
Solution: full white Argentina 2006, Japan 2006 and USA 2006 kits would probably solve the issue.
I think it would make sense to have at least 4 kit variations for WC/Euro teams:
home shirt + home shorts
home shirt + away shorts
away shirt + away shorts
away shirt + home shorts
+ possible additional variations with socks
For example Russia never wore full red kits during WC2018, but right after the tournament they played vs Germany with the same kits and wore full red because white would've clashed with Germany colors:
