Command for showing tracer rounds in demo?

[Disgruntled Sheep ♘]

Hi,

I'm just wondering if there is a console command for showing a tracer round whilst watching a demo. I currently am watching with:

sv_cheats 1
sv_showimpacts 2
r_drawothermodels 2

But I really want to see tracer rounds for a few seconds after the shot. It would look like lasers coming from the weapons and just straigh lines hanging in thin air if it exists. After a lot of shots I'd imagine a lot of spaghetti, so it would have to disappear after a few seconds. Any help greatly appreciated :)

So does anyone know if this can be done...??

sv_showimpacts_time x can extend it (x being the number you want in seconds), but it doesnt show longer than 10
