Animated Shape Shader Suggestion

Hi :-) 

I have a need to animate a value, for example the dashedline offset. 
But I don't want every frame to call from a script that will go to the Shader and GPU. 

I want to do it directly in the shader for offset += _Time * speed;

I followed the project code & conventions and added it to my project. 

Would love to see some more animated values. 

1. Do you plan to add them maybe in the future? 
2. Is there a reason maybe why better that I will not do it? 

Thanks :-)
