How can I auto-increment available options for an integer field? I have a set of available options for an integer field:

2011|2011
2012|2012
2013|2013
...etc


The thing is I want years all the way to 2050. Is there a way to set a step increment in this field? I could create the list in a text editor and paste it, but I'd love to find a more elegant solution using code or some way of incrementing the options.

You can use Microsoft Excel. on A(1) put 2015 on A(2) put 2016. 

Highlight both cells, click on the bottom right corner (you will get a + cursor) and drag down.
