Program Acrobat so all text entered defaults to specific font & size

I am adding text to a pdf by:

• Click Tools to the top right of Acrobat, beneath the X.
• Under Content | Edit Text & Objects, select Edit Document Text.
• Hold down ctrl before you place the cursor on the pdf.

To edit the font size and other properties:

• Select the text, right click, choose Properties and enter the relevant font properties.

This requires me to select every instance of text in a document and manually change the font size. Is there a way to program Acrobat such that all new text entered into the document will automatically default to a specific font and size?
