I would like to have 2 sustain points in my function object so that the envelope plays to the first sustain point then loops between the first and second sustain point until a note off then the envelope plays from the third sustain point to the end. Am I being really daft and there is a simple method to enable me to this? It seems a bit tricky especially as I would like to poly-fy it...

maybe I'm misreading, but you can set as many sustain points as you like. 

Apologies - I've worded my question very poorly. I know how to set the sustain points within the function object. What I am having trouble with is controlling a line~ object using the output of the function object with sustain points. The problem is caused by my desire to have the line~ output loop between the first and second sustain points.

1 - note on - play from start of envelope to first sustain point (the attack/decay part of an ADSR)

2 - note held - play loop from first sustain point to second sustain point until... (the sustain part of an ADSR)

3 - note off - play from second sustain point to end of envelope (the release part of an ADSR)

I am trying to make function behave as an ADSR with an arbitrary number of points at each stage. I can probably kludge together a solution using multiple line~ objects,gates and selector~ but it's not pretty therefore I am wondering if anyone has already done this...

To clarify -
1 - note on - play from start of envelope to first sustain point (the attack/decay part of an ADSR)
2 - note held - play loop from first sustain point to second sustain point until... (the sustain part of an ADSR)
3 - note off - play from second sustain point to end of envelope (the release part of an ADSR)

For the looping, zigzag~ might be useful. A rough example:

zigzag~ was indeed the answer - thanks very much for the pointer! It still seems a bit mucky though...
