UTX-OTIS-CARR RTN - RTX - How to handle multiple Lots and cost basis for these transactions?

Question

Using Q for Win, subscription, latest version.
 Thank you to q_Lurker and others with comprehensive responses and analysis of this complex topic.  My issue is that I had purchased UTX 2 different times over the years and have two Lots in the Security Detail.  How do I maintain the transaction history and cost basis of the individual lots when doing the spinoffs and Corp Name Change sequence?  I don't see how the Wizard takes multiple cost basis lots in to consideration when doing spin-offs.  What am I missing?  Thanks.

Well, the program attempts to do it right -- but currently fails.

I first note that when my prior info was offered, a different Corporate Spinoff action was in use.  The current approach using RtrnCapX, MiscIncX, and Add Shares is the methodology that I see failing for multiple lot holdings.

The total RtrnCap value is correctly calculated using the basis of both (all) lots.  But that RtrnCap action deducts basis from the individual lot in proportion to number of shares when it should be in proportion to the lot's cost basis.

@tas99 My suggestion would be to go at it manually.  A quick review of my prior post I wrote:

In you case there would be two of those ADD Shares in each case.

Post back if you have specific followup questions.
