I am working on a project in after effects where the lower third text information is coming from an external csv file. 
I am new to after effects expressions.
This text will be in 2 or 3 lines and would like to make it lower-third text box width scaled up by using the text length from the 2nd or 3rd line. 
Can you please support me? I am attaching an image for reference. Lower3rds_Reference.JPG

Research the various sourceRectAtTime() methods. Plenty of info out there and even a simple web search will bring up tons of tutorials.

Thanks for your prompt response @Mylenium 

I did try the sourceRectAtTime() method but am not able to put all 2/3 text layers in the same box.

If you happen to have some references or maybe you can help me with the expression, that would be helpful.

 

I also tried the Simple Box Rig method but no luck.
