Pass-through markup on Direct host service fee (single combined owner-facing line)

PMs on Direct Premium want to bill owners a higher % than Hospitable's fixed 7% host fee (e.g. 8% = 7% Hospitable + 1% PM margin) and keep the difference, shown as one combined line on owner statements/invoices/portal — without touching management commission. Today this isn't possible: statements always show Hospitable's actual 7% as its own "Host service fee" line, and there's no way to inflate it or merge a markup into that line. Existing workarounds (manual per-booking adjustments, or increasing management commission) either create extra lines or mix margin into commission.
