You can use the Custom award rule to hand-pick the winners for lots and to combine scenarios. After you edit settings, click Save Changes at the top of the tab.

- Manual override - Manually select winners for lots using specified shares in a bid sheet column. Click the Choose a column list and select the column that specifies the shares that are to be awarded.
If demand is configured, the values indicate the units of demand to be awarded to the bidder. For example, if a lot has a total demand of 50, a value of 40 means the bidder will be awarded 80% of the demand for the lot.
If demand is not configured, the values indicate the percentage of the lot to be awarded to the bidder. For example, a value of 1 means the bidder will be awarded 100% of the lot; a value of 0.5 means the bidder will be awarded 50% of the lot. - Combine scenarios - Use the results from other evaluated scenarios within this scenario. Click the Choose a scenario list and select the scenarios that you want to merge with the current scenario.
For example, if the chosen scenario awards lots 1, 2, and 3, but not lots 4 or 5, the current scenario is used to award lots 4 and 5. If you want to enable the current scenario to award lots 1, 2, and 3, use the override rules at the bottom of the tab.
Enter the lowest number of lot awards that can be overridden in the At least field and enter the highest number of lot awards that can be overridden in the At most field.
Note:
By default, combined scenarios override all lot awards.
