Working with Charts

I’m working on a pattern that flows from regular crochet (sc) to tunisian crochet. The last row before the tunisian crochet starts is an increase row.

With regards to chart symbols, does anyone know if there is a symbol for loops to indicate the ‘cast on’ for tunisian crochet? Ideally, I would want to show two loops above any stitches that were increased in the row below and one loop where there is only one sc. I guess I could leave it off, but it would be helpful to have an indication on the chart that the next row is pulling up loops to start the tunisian crochet. #feedback #tunisian
