channel-ticks on castbar

[Sinaris]

Hello everybody,

im here to search for a little help for my unitframes.
i searched a while on wowi and google, but i found nothing.

Okay, here it is.

I am looking for a castbar channel tick display.
Maybe if a mage is channeling arcane missiles, or a warlock cast drain life or something like this.

I found the castbar spark, try it out and it works.

But the only thing that is missing, is the tha (channel) ticks on my castbar.

Is there any solution for this?
