Yes, boobs will do this, no problems.
As the baby gets older you'd be reducing the no. of feeds anyway, and giving a bottle when you're at work is the same principle.
What you probably can't do is eg. give two feeds a day on your work days, and then four feeds a day at weekends, as you wouldn't have enough milk on Saturday or Sunday, but would then be in agony on Monday when your boobs had adjusted to the extra demand.
So you either have to reduce feeds on nonwork days in line with feeds on work days, or use your weekend feed schedule as a starting point and express the extra on work days. In the long term, the latter might result in a lowered supply. But then again, your baby is at an age where feeds will reduce naturally anyway as she takes more solids.
I'm still feeding morning and evening only, and that works fine. I can sneak in the occasional extra late evening feed at 11pm if she wakes up then, but if she does it more than a couple of days in a row, I feel a bit fuller the next time she sleeps through.
I can't see why you'd have any problems.
