Scenario Planner: Liability if asset (or X% of asset) sold at future price

Would be extremely useful to forward plan tax liabilities for those us planning %-based exits at particular thresholds. A scenario planner for each asset would really separate the service from everything else available the moment.

Example:

–Portfolio information–
1,000 XXXGBP bought at £0.05
Total cost: £500.00

–Scenario planner–
Gain if X% sold at £X: £XX.XX
Estimated CGT liability : £XX.XX

I don’t know if it’s possible, but it would be useful.
