Yes you can create such shapes using a text object.
To create a circle, just add a text object and set its Corner Radius as 360 under the Layout properties of the text object.
Of course, you can assign an action to each of these shapes by right-clicking the object-properties-Action--and then click Add to assign the object an action of your choice.
Please find attachment.
Hope that helps.
