If I'm correct in my assumption, consider the following approach:

Create a single template called something along the lines of `AnalogCardPoint` or similar. Create a parameter called `baseTagPath` and `index`. Create a custom property called tagValue. Create an indirect tag binding on `tagValue` that looks something like `{1}/{2}/Data`. In the box below the indirection string {1} should be linked to `baseTagPath` and {2} should be linked to `Index`

You can then take this template and use it in a template repeater. Create 2 custom properties on the template repeater called `baseTagPath` and `pointCount`. Create a property change script that has a first line that checks if `event.source.propertyName == "baseTagPath" or event.source.propertyName == "pointCount"`. If it does match, build a template paramters dataset with a row count that matches the value of `pointCount`, and place this dataset into the `templateParameters` property of the template repeater.

Technically you could make this template repeater into a template as well, and have `baseTagPath` as a template parameter.

From there, just place enough copies of the template repeater as there are I/O modules and adjust the `baseTagPath` and `pointCount` properties for each to match the respective card.
