Population sequence in building block and default selection

Typically we have many populations in an analysis sequence.

First aspect: When you have a selection in a newly added building block, you get a drop-down list for the populations. I have the impression, that the sequence of the populations is not fixed. The order seems to change. This can be confusing. A consistent sequence would help the human at the computer.

Second aspect: When you calculate properties, you often have several Calculat Proper... building blocks in a row. It would be nice, if the default selected population when you add a building block is the last population you used in another building block. So, you add a first Calculate Intensity block and select your favourite population. When you add the next Calculate Intensity block, that population is automatically selected. Nice!
[currently, the last population I used seems to be moved to the bottom of the drop down list ... the place furthest away! aarrrgh]
