[On Update] → [Set Text:
                  Text = {Format String:
                              Template = "HP: {0} / {1}"
                              Value 0 = {Get Property: prop="health"}
                              Value 1 = 100}]

Build a dynamic save key

[BTCustomTask:
    key = {Format String: Template="save_slot_{0}", Value 0={Get Property: prop="slot"}}
    Range.logic.globalDict[key] = data]

Notes

• Uses Python str.format() — supports all its syntax: {0:.2f} for 2 decimal places, {0:03d} for zero-padded integers.
• Unused values (no placeholder in template) are ignored.
