The option to include charging bands is only available for the NHS scheme, so you would have to create separate items for each charge band and the work out the applicable band for each course manually.
If you decide to do it this way then you can include (Band 1), (Band 2) or (Band 3) as part of the treatment item name to make it easier, i.e. Clinical Exam (Band 1), Root Canal Treatment (Band 2), etc. This will make it easier to work out the charge band when looking at the treatment plan.
You can then add treatment items for the different charge bands and categorise them as Misc treatment items so that can be accessed from the Add Code menu.
If you need any help on creating new schemes then there is a handout that can be downloaded from the Knowledge Base here:
I hope that this helps.
