Comp History: prior year USD allocation skewed based on current spot rate in another currency

Summary:

Is there a setting to "lock" a currency conversion of an element to a historic date?

Content (required):

We grant Long Term Incentive in USD, which is then converted to local currency as of spot rate on grant date.

Fast forward 5 years, when looking at comp history, the value of a historic grant is converted based on today's spot rate. Things may have changed in 5 years so that an award of $10,000 USD converted to local currency shows an inflated value if the currency value has fallen against USD.

USD INR example:

2018 grant                         $10,000 X 70.843561 = 708, 435 (value of the 2014 grant based on currency on that date)
