When you create your custom format, you can define each individual sheet you intend to use. So, for example, you could create a format for sheets 1, 2, 3, 4, etc, up to the total number of sheets you intend to use. The unique characteristics you assign to each sheet will be retained each time you insert a new sheet on your drawing. So, sheet 1 will be as defined, sheet 2 as well, and so on. Once you reach the end of your predefined sheets, all subsequent sheets will have the properties of the last predefined sheet. For example, if you define 3 sheets in your format which we call A, B, and C: Sheet 1 will have the properties of A Sheet 2 will have the properties of B Sheet 3 will have C Sheet 4 will have C Sheet 5 will have C and so on A, B, and C can all have unique notes, title blocks, etc. You can also define custom document properties in the model and call them out in your sheets.
