Ability to combine data from more than 2 surveys 

My company has many products and I often do surveys on multiple products (up to 17). The surveys typically have the same questions -- only the names change.

I would like to be able to combine the data from all the surveys in the reporting tool. I usually have to export everything into SPSS and this takes time.

So, I would like the ability to combine the data from multiple surveys so I can both obtain a true total, as well as compare individual products.

Make it easier to input external data 

The present way to input external data seems clumsy. My understanding is that you give person a unique identifier via the survey link and you can then input the data based on the identifier.

Is there anyway to automate this so that the external data automatically prepopulates the columns of the survey data?

Changing the base for multi-response questions (choose all that apply) 

Currently Question Pro outputs the data by calculation the percentage of all responses given. Thus, for a multi-response question with 6 choices, the percentage chosen for each question is the total number of responses to Question A divided by the total of all the responses to all 6 choices.

I don't find this to be very useful. It would be more useful if the base used for calculation is the number of respondents who answered this question. Thus, I would prefer the results read " 25% of the respondents chose Question A, rather than Question A accounted for 30% of the total responses given to this question.
