Blink to sprint on keyboard

Hi, when I hit space for blink, the char immediately tries to sprint once it blinks. This causes the end of sprint animation and has sometimes caused me to be hit and knocked down. I have been focusing on cast speed, so I'm not sure if this is causing it?

This doesnt seem to happen if I remove blink and just use dodge

Can we please have an option to either:
1) disable the sprint function,
2) have a set timer on how long you need to press dodge before it becomes sprint,
3) or, enable us to rebind sprint to another key?

Thanks
