Flex to LCMs

[rugbylad]

Hi guys, I'm currently on a job where we are changing a ---- load of old t5 panel lights over to LED, in ceiling grids.
Now all these are wired to central LCMs or the occasional Klik and the flexs are no more than 5m.
I feel like I should be throwing a few metal cable ties here there and everywhere to support them but am I right in thinking, as long as they're not getting damaged from the metal grid and they're as short as reasonably practible I don't need to support them?
Advice welcome as it's a time sensitive job and I'm second guessing myself here.

they are supported by the grid, which is steel, so no problem as long as there's no chance of damage to the flexes.

Ceiling grids are not a cable support system.

true, but have you ever seen flexes run in containment, esp. if the installation is existing?
