Matrix question

Hello to everyone, 

I am looking for a solution to simplif my matrix questions. Is there a possibility to create a matrix question where respondant tye in something ? 
For example :  My question regards time spend in different tasks. For now my only possibility is to have percentage (5% of my time to 100%  of the time) on the horizontal axis and the tasks on the vertical axis. What would be wonderful is to have something where they don’t select percentages but they type them in directly so it would be faster for them to do.

I know I can have open questions where they can write number but that would mean to have a question per task which would result in the longest questionnaire ever seen. 

Does anyone know if there is possibility to do something like this?
