You can use another herbicide at the same as using a pre-emergent such as Hi-Yield Weed and Grass Stopper with Dimension as long as you are following the product labels for what you are using. If you are putting down a post-emergent at the same time as your pre-emergent, then you will want to delay watering-in the pre-emergent for at least a day so that you do not wash away the post-emergent. (The Hi-Yield with Dimension must be watered in to be activated.) Most 2,4-D products will control dandelion, but that active ingredient will not kill nutsedge or poa annua.

When using Hi-Yield Weed and Grass Stopper with Dimension, you can either do more frequent applications using less product, or you can use higher rates and apply less frequently. There is an annual maximum rate that you can use, however, so if you are still needing additional weed control, then you may need to alternate with a different pre-emergent product. There is a maximum single application rate of 9.2 lbs per 1000 sq ft, and an annual maximum of 27.6 lbs per 1000 sq ft per year. The 4-4.7 lb rate will give you 3-4 months of control, so if you used that rate 3-4 times annually then you would still be within the annual range.
Keep in mind that not all weeds can be controlled with Dimension, and not all plants can be controlled with any pre-emergent herbicide. So for the best treatment plan, be sure you have identified all the target weeds so you can have a comprehensive treatment plant. Let us know if you need further assistance!
