Hand pollinating tomatoes?

Hi there. I was wondering if anyone knew if it is possible to hand pollinate tomato plants. I live in an apartment building and grow cherry tomatoes in containers on my deck. The exterior of the building is being painted and I have to move everything inside for the next 3 weeks. I have indoor grow lights, so I can keep my plants relatively happy, but I've noticed a few flower buds starting. If the flowers bloom before the painting is done will I be able to pollinate the flowers? Or do I just have to take the loss and hope I get more later in the year?

Thanks.
